I'll do my best to describe what we're seeing happening (I haven't managed to replicate the error in debug mode).
Occasionally we're seeing some odd behaviour from alerts - I've witnessed two things happening:
- Midway through displaying an alert (ours are set for 45 seconds), it will flash off and on, with the message "Alert created and displayed" (or something to that effect) in the bottom left. This seems to reset the timer and the alert will stay up beyond it's 45 seconds.
- We're also occasionally seeing alerts which don't display unless the blank screen button is toggled on and off (it was fluke that I discovered the blank button would show them - we thought they were just not displaying).
I don't know if that's enough to go on but as I say, I've not managed to replicate this in debug mode. At a guess I'd say we're only seeing this 1 in every 4/5 Sundays.
